Sure, you know all the cool bars in the city, but do you know where to find a 45,000-square-foot green roof park or the Benjamin Rush Medicinal Plant Garden? Now you do. The Pennsylvania Horticulture Society (PHS) presents the first walking guide to Center City Philadelphia’s gardens and parks. This colorful map is now available in hotels, SEPTA stations, museums and other attractions citywide, and an expanded version is available here. “The idea [was to] lift up Philadelphia’s most treasured public spaces and some of the hidden gems of the urban landscape,” says Alan Jaffe, PHS’s Director of Communcations. “A guide dedicated to our outdoor assets had not been compiled—until now.”
